CS student and software developer, based in the UK and Finland
My interests include open-source software, agentic LLMs, and privacy-focused technologies. A few examples of personal projects in areas I have enjoyed are listed below, however, this is a limited preview. My full portfolio is available on request.
- Rank-fusion search extension Lightweight fork of SearXNG, rebuilt as a Manifest V2 Firefox extension. Aggregates and re-ranks search results from multiple providers in a minimalistic, ad-free results page. Multisearch queries from lists of trusted sources, e.g., news sites or academic journals, are supported.
- Stargazing chart Offline mobile app tracking and mapping celestial events, such as eclipses or meteor showers. The computations and rendering are done locally, using the Swiss Ephemeris and the user's current location.
- Project Manager Spin on the classic to-do app. An on-device LLM (Qwen 4B) with custom project management skills (e.g. directed acyclic graphs in D2) turns vague notes and end goals into a multi-step, checklisted workflow. Uses web search freely to give tailored, domain-specific steps and prerequisites.
- AI agent Personally maintained open-source Hermes Agent deployed on an Arch-based home server. Connected to all my messaging apps for easy interaction, without using the terminal. I added extensive custom tooling pipelines and skills; e.g. clean text extraction from PDFs via a local OCR model.
